Following the scientific 'double blind study', I put drawings into the testing space of photography. A double negative, a bilateral symmetry, a photogram like effect-- reveal something the drawing was blind to, before it was transformed into a print. The site of drawing is like a lab slide under a microscope, or the forensics of pinned specimens on a wall. If the procedure is modernist, a search for essence, the results are speculative. Just-the-facts yields to primitive science. The air is dense like chalk dust on a blackboard. An approach to life.
